UIWebView与CRITTERCISM冲突

问题描述：
今天做TAG，UIWebView有时正常。有时无任何显示，并报如下错误：

2013-12-05 14:49:49.028 TAG[2680:c817] void SendDelegateMessage(NSInvocation *): delegate (webView:decidePolicyForNavigationAction:request:frame:decisionListener:) failed to return after waiting 10 seconds. main run loop mode:

问题解决：
网上搜了一圈。原因是UIKit不支持多线程，必须在主线程上修改。具体原因是UIWebView是CRITTERCISM冲突，UIWebView需要在CRITTERCISM前初始化，但是项目里办不到。因为项目用了Segment.io，所以直接off了。

升级后iOS后上传审核Architectures问题

问题描述：今天Geely的iPhone版本要上架，用Application Loader上传报错，如下：

iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6

问题分析：显然问题出在升级iOS5后的配置问题上。

问题解决：在Target的Build Settings里，找到Architectures，点击"Standard(armv7)"，再点"Other..."，把原来的内容删掉，在分两行输入"armv6"和"armv7"，搞定。

iOS5结构体编译严格

问题描述：今天二罗升级iOS SDK5，发现Monster不能编译了。具体报错信息如下：

variable length array of non-POD element type 'b2Vec2'

问题分析：错误指向的是cocos2d里一个结构体数组定义，如下：

b2Vec2 vertices[vertexCount];

问题解决：把其改成指针形式，如下：

b2Vec2 *vertices = new b2Vec2[vertexCount];

搞定了。

UIButton无法改变大小尺寸

问题描述：Touch Team做Stupid。发现4.0以上按钮尺寸正常，而4.0以下按钮会大一倍。按钮点击等都很正常。

问题分析：UIButton的frame和bonus都不能改变其尺寸。尺寸一直是图片的原始大小。因为4.0以下一般都不是高清屏，所以要对原始图片缩小尺寸。

问题解决：仔细检查代码后，[UIButton setImage: forState:]改为[UIButton setBackgroundImage: forState:]，一切ok了。

[UIWindow setRootViewController:]需要4.0以上支持

问题描述：今天Touch Team出Stupid测试版，安装20多台iPhone、iTouch、iPad，都可以安装。但是有一台iPhone（3.1.2）报错，不能安装。注：其他设备基本都在4.0以上。

问题分析：因为是调试安装，所以能看到报错信息，如下：

报错的语句是：

self.window.rootViewController = startViewController;

仔细查看报错信息，发现这句报错：-[UIWindow setRootViewController:]: unrecognized selector sent to instance。查看setRootViewController方法，发现需要4.0以上支持。

解决方案：把出错代码：

self.window.rootViewController = startViewController;

替换为：

if( [[[UIDevice currentDevice] systemVersion] compare:@"4.0" options:NSNumericSearch] == NSOrderedAscending )
[self.window addSubview:self.mainViewController.view];
else self.window.rootViewController = self.mainViewController;

一切ok了。

后台运行App导致无法调试

问题描述：Touch Team做Stupid，调试的时候console报以下问题：
warning: Unable to read symbols for /Library/MobileSubstrate/MobileSubstrate.dylib (file not found). warning: Unable to read symbols for /Library/Frameworks/CydiaSubstrate.framework/Libraries/SubstrateLoader.dylib (file not found). 2011-09-21 12:46:54.465 FSStupid[18953:607] MS:Notice: Installing: com.flipscript.stupid [FSStupid] (550.58) 2011-09-21 12:46:54.489 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/Activator.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/Activator.dylib (file not found). 2011-09-21 12:46:54.752 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/QQInput.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/QQInput.dylib (file not found). warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J3)/Symbols/usr/lib/libsubstrate.dylib (file not found). 2011-09-21 12:46:54.889 FSStupid[18953:607] MS:Notice: Loading: /Library/MobileSubstrate/DynamicLibraries/libstatusbar.dylib warning: Unable to read symbols for /Library/MobileSubstrate/DynamicLibraries/libstatusbar.dylib (file not found).

问题分析：用其他的几台设备测试，一切正常。用有问题的那台机器，然后直接运行，也一切正常。网上查了下，是一些后台运行的程序可能搞鬼（如报错信息中的：QQInput.dylib、libstatusbar.dylib等）

问题解决：用Cydia删除一些dylib，就没有问题了。

iPhone 接近传感器 无响应

问题描述：今天施佳音做FSStupid，一个益智类iPhone游戏，需要做接近传感器检测。在单独的例子里是可以运行，但是把同样代码加入到项目中接近传感器没有响应。

问题分析：仔细查找并论证，发现接近传感器只能在竖向的时候工作。

问题解决：把应用程序切换到竖向显示，一切OK了。
